Reapplying Osmo TopOil

juraj.kecso

Hi,

Moved into a house a year ago. Kitchen has wooden worktop treated with Osmo TopOil (Clear Matt 3058). The previous owner left couple of tins behind.

The oil seems to be wearing off and I need to reapply it. This is not something I have done before, so not sure what to do exactly.

Do I need to sand down the existing finish to bare wood (not preferable) before applying new one or can I apply directly on existing finish after giving a good clean?

What is the best way to apply - brush, foam roller, sponge?

Any advice would be much appreciated?

From OSMO's FAQ's

. How do I prepare the wood for re-application and renovating?

For renovating Osmo treated surfaces, no sanding is necessary - as long as you are using the same Osmo product that was used initially to treat the wood and within reasonable time. Re-apply onto a clean and dry surface, usually just one coat is required. Sanding may be necessary if the wood had not been well maintained and there are marks or scratches, two coats would therefore be recommended.

Each product has a varied recommended application method as shown on the product's data sheet as well as the label of the can, which provides best results based on the purpose of the product. The following methods of application may apply:

Brush application: Apply thinly and evenly along the wood grain with a firm, high quality brush and spread well. Remove any surplus or excess with a dry cloth. Usually 1-2 thin coats are required.
Roller application: Apply thinly and evenly along the wood grain with a microfibre roller and spread well. Remove any surplus or excess with a dry cloth. Usually 1-2 thin coats are required.
Cloth application: Apply with a dry, lint-free cloth - thinly, throughly and evenly along wood grain. Remove any surplus or excess with a dry cloth. Usually 3-4 thin coats are required. Please sure to dispose of the cloth safely to avoid ignition.
Spray application: Apply with either a customary spray gun (nozzle 1.2-1.5mm, 1.8-2.5 bar), an airless or HVLP requipment. Apply swiftly in vertical sections along the wood grain.
Buffing application: Spread the finish evenly with a brush, roller or wide paint scraper or an Osmo Scraper. Wait approx. 30-60 minutes for the oil to absorb. Buff the surface with a single-disc machine using a white pad. Apply second coat spreading the finish evenly across the surface using a white pad. 2-3 coats may be required depending on the product being used.

Always trial apply!
